The objective of this study was to determine if Medicare status and age affect clinical outcomes following anterior cervical discectomy and fusion. ⋯ Regardless of age and Medicare status, all patients undergoing cervical discectomy and fusion had significant clinical improvement postoperatively. However, Medicare patients under age 65 have a smaller magnitude of improvement in PROMs.

Mastoidectomy involves drilling the temporal bone while avoiding the facial nerve, semicircular canals, sigmoid sinus, and tegmen. Optical topographic imaging (OTI) is a novel registration technique that allows rapid registration with minimal navigational error. To date, no studies have examined the use of OTI in skull-base procedures. ⋯ This work is the first examining the application of OTI neuronavigation in lateral skull-base procedures. This pilot study revealed the RMS and TRE for OTI-based navigation in the lateral skull base are 1.44 mm (±0.83 mm) and 2.17 mm (±0.89 mm), respectively. This pilot study demonstrates that an OTI-based system is sufficiently accurate and may address barriers to widespread adoption of navigation for lateral skull-base procedures.

Endovascular mechanical thrombectomy (MT) has now evolved to become the standard treatment for acute ischemic stroke due to large vessel occlusion. Arterial perforation is a potential complication of MT, and the risk of this event during blind crossing the occlusion site has been elucidated. The intracranial arterial system shows morphological structural symmetry, so we investigated the utility of the bilateral symmetry of the proximal middle cerebral artery (MCA) as a preprocedural evaluation to predict hidden running course distal to the thrombus. ⋯ The symmetry of bilateral M1-2 structures was demonstrated in most cases from the perspectives of 4 parameters. The MCA symmetry can predict the running course of the MCA before crossing the occlusion site and shows potential benefits for neurointerventionalists.

Programmable shunts play a valuable role in the treatment of hydrocephalus. However, the use of magnets in programming these valves has caused obstacles in today's magnetized world. Previous studies have reported problems with magnetic toys and electronics unintentionally reprogramming shunt valves. This study investigated how an Apple Watch can interfere with the Codman CERTAS Plus electronic programmer. ⋯ The Codman CERTAS Plus electronic programmer detects the magnetic field emitted from an Apple Watch and mistakes it for the valve, rendering programming difficult. These smartwatches and similar electronic devices should be kept away from the programmer and not worn by health care providers to avoid inappropriate readings and setting changes.

Although it is often assumed that preinjury anticoagulant (AC) or antiplatelet (AP) use is associated with poorer outcomes among those with acute subdural hematoma (aSDH), previous studies have had varied results. This study examines the impact of preinjury AC and AP therapy on aSDH thickness, 30-day mortality, and extended Glasgow Outcome Scale at 6 months in elderly patients (aged ≥65). ⋯ Further studies with larger sample sizes are necessary to confirm these observations, but our findings do not support the preconceived notion in clinical practice that antithrombotic use is associated with poor outcomes in elderly patients with moderate or severe TBI.
